Aluminium sulphate (alum) recovery by acidification on the water treatment sludge

Aluminium sulphate (alum) is a solution added to the water to coagulate solids particles in the water. It is to make sure water that sent for domestic use is free of solids particles. This process is called coagulation process. Aluminium sulphate (alum) that coagulated with solids particles forming...
